Abstract: For use with an automatic high speed packaging machine in which products are wrapped and sealed, a control system for a feed conveyer for precisely positioning the incoming products to be wrapped relative to the wrapper's in-feed conveyer. The automatic feeder system leading to the wrapper's in-feed conveyer consists of a plurality of belts and photoelectric eyes are used to sense the presence or absence of product on the belts. The signals from the electronic eyes are applied to a control network to either increase or decrease the speed of selected belts relative to a preceding one to ensure that the product will be fed in a steady stream and at appropriately spaced intervals into the pushers of the wrapper's in-feed conveyer.

Abstract: A multi-sectioned conveyor for receiving serial products from a supply conveyor, inspecting and rejecting out-of-tolerance products and adjustably conveying the products so as to establish a predetermined spacing therebetween, before transferring the products from supporting belts to the individual flights of a pusher member containing conveyor and from which the product flow is synchronized relative to an infeed conveyor to a wrapping station. The feeder comprises a microprocessor controlled, DC driven accumulation, transition and backlog conveyors, along with wrapper driven separation, transfer and infeed conveyors.

Abstract: A wrapping machine which includes a film former for shaping a continuous film of packaging material into a continuous tube, a film drive for drawing the continuous film of packaging material past the former and past a cutting and sealing station, a product infeed drive for feeding products to be packaged through the former into the continuous tube of packaging material so that the products are spaced apart from one another in the tube, and a motor-driven rotary cut/seal head at the cutting and sealing station for cutting and sealing the continuous tube of packaging material as each product moves through that station. The wrapping machine also includes independent closed-loop servo-control circuits for the film drive, the product infeed drive, and the cut/seal head drive, each of which is responsive to a desired velocity control signal.
